SP813LCP-L Equivalent & Substitute Parts

Part Overview

The SP813LCP-L is a single-channel power supply supervisor IC manufactured by MaxLinear, Inc., designed for power-on reset and voltage monitoring applications. This device operates as a simple reset controller with active-high output and a 140ms minimum reset timeout. The SP813LCP-L is classified as an obsolete product, making equivalent substitute parts necessary for new designs and ongoing production requirements. Functionally equivalent alternatives are available in both through-hole and surface-mount packaging options with extended or standard operating temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SP813LCP-L is determined by the following critical electrical and mechanical parameters:

Core Functional Requirements:

• Single-channel voltage monitoring at 4.65V threshold
• Simple reset/power-on reset topology
• Active-high reset output
• 140ms minimum reset timeout

Acceptable Variations:

• Mounting type (through-hole to surface-mount conversion permitted)
• Operating temperature range (extended range acceptable for standard range applications)
• Output stage configuration (push-pull/totem-pole output compatible with active-high reset logic)
• Packaging format (DIP to SOIC conversion, or tube to tape & reel)

Non-Substitutable Parameters:

• Voltage threshold (must remain 4.65V)
• Reset polarity (must remain active-high)
• Reset timeout specification (must meet 140ms minimum)
• Number of monitored channels (must remain single-channel)

Three substitute parts meet these criteria and are grouped by packaging and thermal characteristics.

Engineering Selection Recommendations

SP813LEN-L/TR (MaxLinear, Inc.) Select this substitute for new surface-mount designs requiring extended operating temperature range (-40°C to 85°C). This part maintains MaxLinear manufacturing lineage and is actively produced. The 8-SOIC package reduces board footprint compared to through-hole DIP options. Tape & reel packaging supports automated assembly processes. RoHS compliance status not specified in available data.

MAX813LCPA+ (Analog Devices Inc./Maxim Integrated) Select this substitute for through-hole applications with standard operating temperature requirements (0°C to 70°C). This part provides direct package compatibility with the SP813LCP-L in 8-DIP format. Push-pull output stage offers improved drive capability. ROHS3 compliance and REACH unaffected status confirmed. Suitable for legacy board designs requiring minimal layout modifications.

MAX813LEPA+ (Analog Devices Inc./Maxim Integrated) Select this substitute for through-hole applications requiring extended operating temperature range (-40°C to 85°C). This part maintains 8-DIP package compatibility while providing thermal performance beyond the original SP813LCP-L specification. Push-pull output stage and ROHS3 compliance provide modern manufacturing standards. Recommended for applications with demanding environmental or reliability requirements.

Frequently Asked Questions (FAQ)

Q: Can SP813LEN-L/TR replace SP813LCP-L in existing through-hole designs? A: No. SP813LEN-L/TR uses 8-SOIC surface-mount packaging, which is not compatible with through-hole PCB layouts. Use MAX813LCPA+ or MAX813LEPA+ for through-hole board designs.

Q: What is the difference between MAX813LCPA+ and MAX813LEPA+? A: Both parts are functionally equivalent with identical electrical specifications. The primary difference is operating temperature range: MAX813LCPA+ operates 0°C to 70°C, while MAX813LEPA+ operates -40°C to 85°C. Select MAX813LEPA+ for applications requiring extended thermal performance.

Q: Are all substitute parts RoHS compliant? A: MAX813LCPA+ and MAX813LEPA+ are ROHS3 compliant. RoHS status for SP813LEN-L/TR is not specified in available documentation.

Q: Can I use a substitute part with a different output stage configuration? A: Yes. MAX813LCPA+ and MAX813LEPA+ feature push-pull/totem-pole output stages, which are compatible with active-high reset logic applications. This output configuration provides improved drive capability compared to standard output stages.

Q: Does operating temperature range affect substitution compatibility? A: Extended operating temperature range (-40°C to 85°C) is acceptable as a substitute for standard range (0°C to 70°C) applications. The substitute will operate correctly across the original temperature specification and beyond. Standard range parts cannot substitute for extended range requirements.

Q: What packaging considerations apply to surface-mount substitution? A: SP813LEN-L/TR in 8-SOIC package requires surface-mount PCB layout and assembly processes. This part is not compatible with through-hole designs. Tape & reel packaging supports automated pick-and-place assembly.
